Abstract

Pemanfaatan batu bara dan biomassa untuk menghasilkan panas dan daya semakin meningkat seiring dengan kebutuhan energi yang semakin tinggi. Cadangan batu bara Indonesia yang sebagian besarnya adalah batu bara kualitas rendah, menarik untuk diteliti bersamaan dengan pemanfaatan biomassa. Sehingga tujuan dari studi ini adalah melakukan investigasi pengaruh perbandingan udara bahan bakar suatu tungku pembakaran bersama antara biomassa dan batu bara. Penelitian dilakukan secara simulasi computer menggunakan perangkat lunak ASPEN PLUS. Hasil dari penelitian menunjukkan pemodelan termodinamika dengan ASPEN PLUS mampu menyimulasikan pembakaran bersama antara biomassa dan batu bara. Penambahan biomassa menurunkan temperatur gas pembakaran dari 900°C menjadi 400°C sehingga menurunkan kadar NOx dan SOx. Pengaruh excess air menurunkan temperatur pembakaran. Efisiensi tungku pembakaran bersama antara biomassa dan batu bara diatas 60% dan dipengaruhi oleh komposisi campuran.
